This study evaluates user satisfaction with the Testing Monitoring System using the End-User Computing Satisfaction (EUCS) model. The evaluation focuses on five dimensions: content, accuracy, format, ease of use, and timeliness. A descriptive quantitative approach was employed, involving 12 users of the Testing Monitoring System as respondents. Data were collected through a questionnaire using a five-point Likert scale and analyzed using descriptive statistics to determine the mean score and satisfaction percentage for each EUCS dimension. The results indicate a very high level of user satisfaction across all dimensions. The content dimension obtained the highest mean score of 4.46, corresponding to 89%, followed by timeliness with a mean of 4.42 or 88%. Accuracy and format achieved mean scores of 4.37 and 4.33, respectively, with both reaching 87%, while ease of use recorded the lowest mean score of 4.28 or 86%. Overall, the Testing Monitoring System achieved an average mean score of 4.37, equivalent to a user satisfaction level of 87%, which falls within the very high category. Despite these positive findings, improvements are still required, particularly in the user-friendliness of the system and the attractiveness of its interface, as these indicators received the highest proportion of neutral responses. The findings demonstrate that the Testing Monitoring System generally meets user expectations and that the EUCS model can effectively identify specific aspects that should be prioritized for further system improvement.
